    Cache a few bits of status in jqueue · 20571a26
    Guido Trotter authored
    Currently each time we submit a job we check the job queue size, and the
    drained file. With this change we keep these pieces of information in
    memory and don't read them from the filesystem each time.
    Significant changes include:
      - The drained value can only be properly set by calling the
        appropriate cluster command "gnt-cluster queue drain/undrain" and
        not by removing/creating the file in the job queue directory. Not
        that anybody would have done it in this undocumented way before.
      - We get rid of the soft limit for the job queue, which we haven't
        ever used anyway.
